Ivan,

I think I disagree with you on this point.

This is actually a very important goal: to have a blogging use case. We
don't want people to think that RDFa is "just for complex scientific
data." It should be usable for simple things, too.

That's just extra data that your newsreader can choose to ignore. The
point is that the same source can be both a rendered HTML page and a
newsfeed.

Okay, but that's your blog tool that has to keep everything in sync on
the backend by re-baking your site, or by dynamically responding to new
queries. This lets you build *much simpler* blog engines. I've added a
short mention of this.

Sure, but then we lose the use case that the bloggers will flock to. I
think we need to keep in mind that bloggers are a huge constituency, and
we need to take their needs into account specifically.

I'm a bit confused as to why this is bothering you. Having extra data is
not a problem in RDF, right?

Yes, that's more or less what my latest edit says.

Check it out and let me know if this makes sense.
